  Can anyone give me pointers to language prototyping/description
systems? The only available ones I am aware of are:

	HLP - The Helsinki Language Processor
              I think a copy of this was posted to the net a while back.
              Attribute grammar based, uses a stack evaluator.
        GAG - Available from the University of Karlsruhe (?)
              Also attribute grammar based, uses a general deterministic
              algorithm for attribute evaluation
        Qparser - Commercially available, distributor unknown,
              looks similar to HLP
        Kodiyak/AG - Available from the U of Minnesota
              Attribute grammar based, uses a general deterministic
              algorithm for attribute evaluation
